Leak Location & Air Current Detection

Air Current Testers

An essential tool for finding leaks in your enclosure, each Retrotec Air Current Tester creates about 1000 puffs of smoke, has an indefinite shelf life until activated and comes in an airtight case.

Air Current Testers are often called smoke puffers. The smoke puffer has a perfect neutral buoyancy smoke stream that makes it easy for you to see invisible air leaks in ductwork and thermal envelopes.

Your Air Current Tester Comes packed in an airtight storage tube with 2 spare nozzles and 1 spare rubber tip. The internal glass vial holds the 10 ml of TiCl~4~ chemical indefinitely prior to charging. Charge by merely folding the tube. No messy chemicals to pour.

Always make sure you have one or two air current testers at your job site!

Test for:

  • Air-flow Direction
  • Room and building Leak location
  • Duct Leakage
  • Energy wasting house leaks
  • Room pressure imbalances
  • Pressure neutralization
  • Backdraft, spillage and heat exchanger leaks

Once activated, the Air Current Tester will produce small or large puffs with excellent control. Long streams can be produced to check for air movement over wide areas or smaller puffs for smaller areas. Hairline cracks can be identified easily.
